The utility model belongs to technical field of motorcycles, specifically, and the ABS front ring gear mounting structure particularly on motor bike.
Background technology
Safety is the most important performance of motor bike, can improve the drive safety of motor bike by installing ABS anti-embracing unit additional, but at home, the motor bike installing this device additional is few.In the anti-enclasp device of ABS, setting accuracy and the reliability of front, front ring gear are extremely important, and before how arranging, front ring gear is the technical matters that numerous Motorcycle Manufacturers is just making great efforts to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dismounting front ring gear mounting structure easily.
The technical solution of the utility model is as follows: a kind of front ring gear mounting structure, comprise front wheel hub (1), front ring gear (2) and front brake disc (3), described front wheel hub (1) is by hub circle (1a), hub (1b) and spoke (1c) are formed, hub (1b) is formed with six circumferentially well-distributed erection columns (1d), each erection column (1d) has screw, the middle part of described front brake disc (3) has deep gouge (3a), the bottom land of this deep gouge (3a) is ring-shaped platform (3b), described ring-shaped platform (3b) fits with the end face of upper six erection columns (1d) of hub (1b), its key is: each erection column (1d) is equipped with a thru-bolt (4), the inner of this thru-bolt (4) is passed the via hole on ring-shaped platform (3b) and stretches in the screw of erection column (1d), front brake disc (3) and hub (1b) are linked together, boss (4a) compressing that thru-bolt (4) is integrally formed is on the ring-shaped platform (3b) of front brake disc (3), in the deep gouge (3a) of described front brake disc (3), front ring gear (2) is set, the inner circle of this front ring gear (2) is formed with six circumferentially well-distributed flanges (2a), flange (2a) and thru-bolt (4) one_to_one corresponding, and flange (2a) abuts on the end face of thru-bolt (4) boss (4a), make the outer end of thru-bolt (4) through the assembly opening (2b) in corresponding flange (2a), and locked by nut (5).
The utility model utilizes the attachment point of front brake disc on front wheel hub, adopts six thru-bolts to connect front ring gear, front brake disc and front wheel hub, and mounting process is simple, and dismounting is convenient, and efficiency of assembling is high.Thru-bolt is formed with boss, front brake disc compresses by an end face of this boss, another end face of boss is located front ring gear, guaranteeing that front brake disc and front ring gear are installed firmly simultaneously like this, front ring gear can not occur axially or circumference moves, precision is reliable, can guarantee that ABS wheel speed sensors obtains the accuracy of signal.The utility model does not change the structure of front wheel hub and front brake disc, substitutes traditional plain bolt, increase productive costs hardly with thru-bolt.Meanwhile, front ring gear is arranged in the deep gouge of front brake disc, and front ring gear does not additionally take up room, and does not affect mounting means and the position of front brake disc.
In order to simplified structure, facilitate processing and fabricating, described front ring gear (2) is by punch forming, and flange (2a) is in the same plane with the base portion of front ring gear (2).
Conveniently disassembling operations, as preferably, the boss (4a) on described thru-bolt (4) is positive hexahedron.
For the ease of processing and fabricating, described front wheel hub (1) is formed by the casting of aluminum alloy essence.
Beneficial effect: the utility model uses the attachment point of front brake disc on front wheel hub dexterously to assemble front ring gear, make that the mounting structure of front ring gear is simple, precision is reliable, disassembling operations is all very convenient, and do not change original structure, on various types of motor bike, transformation is very easy to.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is made up of front wheel hub 1, front ring gear 2, front brake disc 3, thru-bolt 4 and nut 5.Wherein, front wheel hub 1 is formed by the casting of aluminum alloy essence, and comprise hub circle 1a, hub 1b and spoke 1c tri-part, the structure of front wheel hub 1 is same as the prior art, does not repeat at this.Hub 1b is formed with six circumferentially well-distributed erection column 1d, each erection column 1d has screw.Front brake disc 3 is positioned at the side of hub 1b, and the middle part of front brake disc 3 has deep gouge 3a, and the bottom land of this deep gouge 3a is ring-shaped platform 3b.The end face of upper six the erection column 1d of ring-shaped platform 3b and hub 1b fits.Each erection column 1d is equipped with a thru-bolt 4, and the inner and the outer end of this thru-bolt 4 are all processed with screw thread, is provided with boss 4a between two sections of screw threads, and this boss 4a and thru-bolt 4 are structure as a whole, and boss 4a is preferably positive hexahedron.
As shown in Figure 1, Figure 2, Figure 3 shows, the inner of thru-bolt 4 is passed the via hole on ring-shaped platform 3b and stretches in the screw of erection column 1d, front brake disc 3 and hub 1b is linked together.The boss 4a that thru-bolt 4 is integrally formed oppresses on the ring-shaped platform 3b of front brake disc 3.In the deep gouge 3a of front brake disc 3, arrange front ring gear 2, this front ring gear 2 passes through punch forming.The inner circle of front ring gear 2 is formed with six circumferentially well-distributed flange 2a, and the base portion of flange 2a and front ring gear 2 is in the same plane.Flange 2a and thru-bolt 4 one_to_one corresponding, and flange 2a abuts on the end face of thru-bolt 4 boss 4a, makes the outer end of thru-bolt 4 through the assembly opening 2b on corresponding flange 2a, and is locked by nut 5.
